    Fireplaces, Woodstoves, and Clean Air in Pima County

    Pima County Department of Environmental Quality 33 N. Stone Avenue, Suite 700 Tucson, AZ 85701 520-724-7400 www.pima.gov/deq January 2016 Fireplaces, Woodstoves, and Clean Air in Pima County Wood burning is of concern in our community because it is not healthy to breathe wood smoke. Smoke is made up of a complex mixture of gases and fine particles produced when wood burns. According to 2002 estimates, there are approximately 70,000 households that burn wood in fireplaces or wood burning stoves within Pima County. The wood burned by these devices emits about 3,100 tons of carbon monoxide (CO) and particulate matter (PM) into our skies annually, in addition to other pollutants and potentially cancer-causing materials. These microscopic particles in wood smoke can be inhaled deep into the respiratory system where they may cause serious health impacts. The combination of altitude, topography, longer nights and cool winters adds to the wood smoke pollution problem in Pima County. On cold nights with little wind, layers of warm air above trap cold air in the valley, forming an inversion. This inversion layer acts like a blanket and keeps smoke and other pollutants close to the ground. These stagnant conditions can last for days and impact the health of our neighbors. Check with your neighbor to see if your fireplace smoke is causing problems with their health. Together, we can spare the air of these harmful pollutants by choosing not to use our fireplaces as much, or by making small changes in our wood-burning practices. Wood Burning Tips Use firewood that has been dried for longer than six months.

    Fast Facts (PDF)

    FAST FACTS According to the National Fire Protection Association, the leading factor contributing to home heating fires (30%) was mainly due to having a dirty chimney (i.e., creosote buildup). Heating equipment (including wood stoves) is the second leading cause of home fires, and third leading cause of home fire deaths. Most fireplace and chimney fires are caused by creosote buildup, and could be prevented. EPA believes there are approximately 13 million fireplaces, 250,000 hydronic heaters, and 8.5 million wood stoves in use nationwide. Five million (57 percent) of the nation’s wood stoves are older, inefficient devices. EPA estimates that if all of the old wood stoves in the United States were replaced with cleaner- burning hearth appliances, an estimated $56-126 billion in health benefits per year would be realized. Smoke from wood-burning stoves and fireplaces contain a mixture of harmful gases and particle matter (PM2.5). Breathing these small particles can cause asthma attacks and severe bronchitis, aggravate heart and lung disease, and may increase the likelihood of respiratory illnesses. Changing out one old dirty, inefficient wood stove is equivalent to the PM2.5 reduction of taking five old diesel trucks off the road. The benefits of replacing old wood stoves and fireplaces: • Saves money, fuel, time, and resources • Up to 50 percent more energy efficient, uses 1/3 less wood • Cuts creosote build-up in chimneys that helps reduce the risk of fire • Reduces PM2.5 indoors and out After start-up, a properly installed, correctly used EPA-certified wood stove should be smoke free.

    AP-42, Vol. I, CH1.9: Residential Fireplaces

    1.9 Residential Fireplaces 1.9.1 Generall-2 Fireplaces are used primarily for aesthetic effects and secondarily as supplemental heating sources in houses and other dwellings. Wood is the most common fuel for fireplaces, but coal and densified wood "logs" may also be burned. The user intermittently adds fuel to the fire by hand. Fireplaces can be divided into 2 broad categories: (1) masonry (generally brick and/or stone, assembled on site, and integral to a structure) and (2) prefabricated (usually metal, installed on site as a package with appropriate duct work). Masonry fireplaces typically have large fixed openings to the fire bed and have dampers above the combustion area in the chimney to limit room air and heat losses when the fireplace is not being used. Some masonry fireplaces are designed or retrofitted with doors and louvers to reduce the intake of combustion air during use. Prefabricated fireplaces are commonly equipped with louvers and glass doors to reduce the intake of combustion air, and some are surrounded by ducts through which floor level air is drawn by natural convection, heated, and returned to the room. Many varieties of prefabricated fireplaces are now available on the market. One general class is the freestanding fireplace, the most common of which consists of an inverted sheet metal funnel and stovepipe directly above the fire bed. Another class is the "zero clearance" fireplace, an iron or heavy-gauge steel firebox lined inside with firebrick and surrounded by multiple steel walls with spaces for air circulation. Some zero clearance fireplaces can be inserted into existing masonry fireplace openings, and thus are sometimes called "inserts".

    F I R E P L A C E S Y S T E M S The affordable heat-circulating fireplace offering style, value and performance. After a Hard Day in a Cold World… The NEW-AIRE FIREPLACE SYSTEM utilizes the basic principles of thermodynamics designed into any new high-efficient forced air furnace (radiant, conductive and convective heat transfer). By forcing air movement through a series of baffles in a specifically designed heat exchanger surrounding a steel firebox, ratings in excess of 200,000 BTU can be achieved in a full-fired condition. With 1050 cubic feet of air per minute at central HVAC static pressures, the NEW-AIRE fireplace easily matches the heat output of any high-efficiency furnace on the market today. Your home is the heart of your family’s life. A warm hearth is the gathering place that defines the spirit of the home. The NEW-AIRE fireplace, clad in brass and glass, provides both the traditional and functional elements needed in today’s life. Unlike stoves and inserts, the NEW-AIRE can be independently ducted to provide whole-house heating beyond the walls of the room in which it is installed. Certified to the International Mechanical Code, when ducted to induce heat into the central heating system, the NEW-AIRE SYSTEM efficiently provides the required heat for 4000 plus square foot homes. The NEW-AI Airtight /Airwash Door Control: heat loss, wood consumption, and smoke in the winter — air infiltration and ash smell in the summer. Makes any fireplace more efficient by controlling the “burn rate”.
